Selective herbicidal compositions

Abstract

This invention discloses herbicidal compositions which selectively destroy weeds in cereal grain without damaging said grain plants, comprising in combination an anilide of the formula ##STR1## wherein Y is selected from the group consisting of hydrogen, lower alkyl and halogen; R 1 is selected from the group consisting of hydrogen, lower alkyl and lower alkoxy; R 2 is lower alkyl; R 3 is selected from the group consisting of hydrogen and lower alkyl; X is halogen; n is an integer from 1 to 2; Z 1 and Z 2 are independently selected from the group consisting of oxygen and sulfur; R 4 , R 5 , R 6 , and R 7 are independently selected from the group consisting of hydrogen and lower alkyl; and m is an integer from 0 to 2; and from 0.01 to 15.0 weight percent of said anilide of a compound of the formula ##STR2## wherein R 8 and R 9 are each selected from the group consisting of alkyl, alkenyl, alkynyl, haloalkyl, haloalkenyl, haloalkynyl, alkoxyalkyl, halogen-substituted alkoxyalkyl, alkenyloxyalkyl, halogen-substituted alkenyloxyalkyl, cycloalkyl and cyanoalkyl; and wherein R 8 and R 9 together with the nitrogen atom can form a 5- to 7-membered heterocyclic ring which optionally contains an additional heteroatom and which optionally is substituted with alkyl.

I claim: 
     
       1. Herbicidal compositions which reduce injury to corn from the treatment of herbicides comprising in combination an herbicide of the formula ##STR5## wherein Y is hydrogen; R 1  is lower alkyl; R 2  is lower alkyl; R 3  is hydrogen; X is chlorine; n is 1; Z 1  and Z 2  are oxygen; R 4 , R 5 , R 6  and R 7  are hydrogen; and m is 0; and from 0.01 to 15.0 weight percentage of said herbicide of an antidote for said herbicide of the formula ##STR6## wherein R 8  and R 9  are lower alkenyl. 
     
     
       2. An herbicidal composition comprising an inert carrier and as an essential active ingredient in a quantity toxic to weeds, a first compound consisting of an herbicide of the formula ##STR7## wherein Y is hydrogen; R 1  is lower alkyl; R 2  is lower alkyl; R 3  is hydrogen; X is chlorine; n is 1; Z 1  and Z 2  are oxygen; R 4 , R 5 , R 6  and R 7  are hydrogen; and m is 0; and from 0.01 to 15.0 weight percentage of said herbicide of an antidote for said herbicide of the formula ##STR8## wherein R 8  and R 9  are lower alkenyl. 
     
     
       3. The composition of claim 2 wherein the first compound is N-α-chloroacetyl-N-(1,3-dioxolan-2-ylmethyl)-2,6-diethylaniline. 
     
     
       4. The composition of claim 2, wherein the first compound is N-alpha-chloroacetyl-N-(1,3-dioxolan-2-ylmethyl)-2,6-dimethylaniline. 
     
     
       5. A method of controlling weeds in corn which comprises contacting the locus of said weeds with a herbicidal composition of claim 2.
